Fig. 2 is aventral vertical section. Kim 3 shows details of various shapes-of the jet orifice. -for purposes to be hereinafter referred to.

Referring specifically to the drawings (3 indicates a bowl or cup. This may he. made of metal or pottery, and is of sufiicient depth and size to surround thestream and take care of the :WtlStt. water which escapes through the paste trap-7 at the bottom. This trap isof novel construction and forms the sub e-ct of a separate application for patent.

In the side wall of the bowl an opening 8.

.65 is produced directed inwardlv and upwardly, and on the inside of the bowl,

ondifibhscharaie'ristieofsbxiie of the drm' 16x thereto. r

The water is supplied through the pipe 12, .which may be controlledby a push valve 13 lea-swam n the 'nppelr side b sessions r splasli gainsttli ing, so that it will run down' .the .rn UFOf:

openings This. is eflecte by beading the" rim, to form a channellOarourid. the=same.

Above this opening, the inneriwall of the bowl is p'rovidedwith a shieldorprojection .11 which overhangs the openingand-pre-;

vents the drinker from applying'his; tnouth;

and thi's' pip'e leads to'a head'l i which is, spaced from the exterior of the bowl, the

vided on the side adjacent to the bowl-with a nozzle 18 directed upwardly andinwardlyfl in line with the opening 8. and above the] nozzle the head has a chamber 19 in which air is trapped to prevent water hammer and insure a regular flow.

The. size of the nozzle 18 is suchithat the i stream of water. discharged therefi'on js;

smaller than the'opening 8, so that \vliar water is (,liseharged through the nozzle airis entrained therewith as-il. passes through-Hf the opening 8.

The form and construction of the parts are such that the'stream of water describes a paraholie curve in the bowl. with its crest just above the top of the bowl and suhsl'antially at the aiiis thereof. The mouth of the drinker is applied to the stream at this'crrst. stream the form of the jet may be varied to break up and aerate the same. Several ofthese forms are iliustrated' in Fig. 3. Thus the orifice of thenozzle maybe in the shape of an oval. a cross, or a para Hologram which will have the affect of cut-raining :lll at the nozzle and at'iheopening S-to given sparklin; strewn of appelizius; n])])":ll':lll(.(..

As the stream pas es through the. opening 8 it clears the sides thereof and avoids any danger of contaminationfrom matter colleoted on or in the bowl. The nozzle is also out. of contact with the howl and there is In" order to give a sparkling' Ian danger of germs spreading from the bowl to the nozzle. The nozzle is protected from the waste water. and should any splash or -between the opening and the nozzle.
